Natural phenomenon needn’t be mysterious. Ponder Aurora Borealis, arguably one of nature’s greatest phenomenon, least mysterious spectacles. Aurora are offspring of space weather, nothing mysterious about that. On May 11, 2020 Earth is expected to cross a fold in the heliospheric current sheet. In less mysterious language – disruption of interplanetary space separating opposing magnetic polarities of Earth and Sun, briefly over riding Earth’s magnetic field, inviting solar energy to temporarily dazzle sky watchers with aurora majesty – consider yourself schooled in solar sector boundary crossing, a space weather basic.
Solar wind is the source of space weather. Just like Earth, the Sun has a magnetic field known as interplanetary magnetic field (IMF). Whipped into spiral rotation, wind driven IMF rotates in one direction dividing into spiral sections pointing to and away from the sun along an ecliptic plane ( direct line between Earth and the Sun). The edge of this swirling mass has a surface separating polarities of planetary and solar magnetism called the heliosphere current sheet.
Earth’s magnetic field points north at the magnetopause (the point of contact between our magnetosphere and the IMF). If the IMF happens to point south at contact the field link causes partial cancellation of Earth’s magnetic field – in other words, opening a temporary door for solar energy to enter our atmosphere. Welcome solar sector boundary crossing – a phenomenon born of high solar wind and coronal mass ejections (CME’s – aka solar flares).

Seeing is believing, pictures speak a thousand words, right? Not so fast – ponder photographic perspective. Swedish photographers Olafur Steinar Gestsson and Philip Davali conducted a little experiment for photo agency Ritzau Scanpix. The premise was simple, capture images of the same subject matter at the same time from two perspectives. One with telephoto, the other a wide angle camera lens.
For weeks my photographer husband has criticized headline images of irreverent social distancing. Not to say it doesn’t exist, far from it. That said, it’s worth pondering how telephoto images are used to sway, reinforce or punctuate public perception. Now I get it.
A compilation of 1,200 images taken over four days by Mars rover Curiosity resulted in this 1.8 billion pixel resolution panoramic postcard from Mars. Struggling to express how remarkable this is, I’m acutely aware of how happy it makes me.
On August 5, 2011 NASA’s Juno mission left Earth orbit, destination Jupiter. The farthest space probe ever to be powered by solar arrays, Juno arrived in orbit around Jupiter on July 4, 2016. Every 53 days Juno completes one orbit of Jupiter. Close orbital passes are called perijoves, from the Greek word peri which means near. Images from Juno’s latest close approach, ( perijove 25 completed on February 27, 2020 ) were made public this week by NASA.

It’s been a tough week, when things get tough I turn to timelapse. Serendipity introduced Yosemite Channel by Barry Chall, retired professional photographer and digital artist turned dark sky visual custodian. Take a deep breath, relax with a journey through the sky….
I can’t think of a better way to welcome the new year than gorgeous timelapse from Adrien Mauduit at Night Lights Films. Timelapse photography is a immensely powerful artform, one capable of reinventing personal definitions of this place called Earth. Few do it better than Adrien Mauduit. Happy New Year from Notes.
In the words of Adrien Mauduit at Night Lights Films –
“There are only a few regions in the world where the skies meet the Earth with almost no distinction between the two. La Palma in the Canary islands is one of them. ‘Entre Ciel et Terre’ literally means ‘Between the sky and Earth’ and was a perfect fit here. While most of the volcanic island is isolated under a thick layer of clouds, the tip of its crater often punches through it and allows you to be one step closer to the Heavens. At an altitude of about 2300 meters above sea level you feel so far removed from any kind of civilization especially because of the cloud inversion. The air is thin and pristine and the living conditions are harsh but that’s the reason why the ORM (Observatory Roque de Los Muchachos) -operated by the IAC (Instituto de Astrofísica de Canarias) and part of the European Northern Observatory, was built up there. The summit of La Palma’s caldera benefits from dry and clear skies almost year round with almost no light pollution to disturb it, and only rare Calima (this dusty wind coming from the Sahara desert). It’s safe to say that the ‘Isla Bonita’ is one of the top places in the world to observe the northern hemisphere’s night sky!
The purpose of this short was to capture that special place from a different perspective. I really wanted to give the audience sort of a confusion as to where they are because that’s precisely the feeling you get when you look up at the stars from the mountains. You somehow lose sense of any orientation as if you were lost in the immensity of the universe! One image that I had in my head to describe La Palma’s summit was Asgard or Mount Olympus, where all the elements are united and blend together divinely. Even life found a way to survive in this environment bombarded by high-energy rays during the day and battered by cold winds at night. One highlighted species is the fascinating and mind-boggling Tajinaste flower. Also called Tenerife Bugloss or tower of jewels, this docile and resilient endemic plant can endure extreme drought. I included it in the movie because it looks majestic and prehistoric. It really adds something special to the special atmosphere I wanted to convey, especially when the milky way galaxy and the sea of clouds move in the background! By tracking the night sky or displaying the sequences upside-down I was able to give that impression of the Earth floating and rotating in the void of the cosmos. The unusual but innovative close-up views of some parts of the milky way (including the core, Rho Ophiuchi or Cygnus) moving behind the operating telescopes of the OMC helped me give that only human dimension to the movie. The use of an astro-modified camera also enabled me to almost get the full range of colors a DSLR can pick up on single frames from nebulae.
I already traveled to La Palma island in November 2017 but I really wanted to shoot there again for several reasons. First I really wanted to get more shots of the core region that would be less spoiled by light pollution than the ones I recently took on Tenerife. Secondly I desperately wanted to meet the extremely talented photographer Alyn Wallace (check him out: alynwallacephotography.com) and do a collaboration with him on the island. Thirdly I am still on my way of perfecting the novel art of deep-sky time-lapse and I wanted to reshoot some sequences that didn’t give satisfying results in the past. Finally I wanted to personally experience the Spring vibe of the island when all the plants are blooming and give that sweet smell to the air. I am absolutely thrilled to have met all my expectations (and more!), and I really believe the results look stunning!
Everything was recorded with the Canon 6D Baader modified, the Sony a7s, the Sony a7rII and a variety of bright lenses ranging from 14mm to 300mm. I used the Lonely Speck Pure Night and Matt Aust Light pollution filters to reduce light pollution and increase details, and also the Vixen Polarie to track the stars and get cleaner shots. Syrp Genie 3 axis system was used for motion control. All post production was made in Lr with the special timelapse plus plugin, Sequence for mac, TLDF, and final production was made in FCPX. I hope you like the movie as much as I liked shooting and processing it and I thank everyone of you for your support.
